Question

What is the property of real numbers illustrated by the equation: `2sqrt(7) * sqrt(3) = 2(sqrt7 * sqrt(3))`?

Answer 1

Associativity of multiplication

Explanation:

Multiplication of Real numbers is associative.

That is:

`(ab)c = a(bc)`

for any Real numbers `a`, `b` and `c`

`color(white)()`
Footnote

Multiplication of Complex numbers is also associative as is multiplication of Quaternions.

You have to go to some really strange numbers such as Octonions before multiplication is not associative.
